Apple iPod 5th Gen refurb restock?

How often does Apple generally get replacement stock for refurb items?

I'm eyeing a 5th gen 32gb iPod touch as a holiday gift. Several sites have it available for ~$280 new (cyber monday price?). As of this writing, Apple is out of their refurb 5th gen iPod touch 32gb model. I don't want to miss out on the $280 price, but will wait a bit if I can be fairly sure to get a refurb from the Apple store. Input appreciated.
